Halls ICON 6 6x8 Greenhouse - mill with 3mm toughened glass

Upgrade your growing space without overpowering your garden. The Halls ICON 6 6x8 Greenhouse provides a practical increase in room, making plant care, organisation, and everyday use more comfortable. 

Enjoy a well-proportioned greenhouse designed to maximise usable space without dominating your garden. The extended 6x8 size gives you freedom to arrange plants, staging, and walkways comfortably while sitting neatly within most garden layouts. Designed as a freestanding structure, it offers improved airflow, higher eaves, and a more stable internal climate for watering, potting, and everyday plant care, delivering the comfort of a generously sized greenhouse without overwhelming your outdoor space.

Built with a durable mill-finish aluminium frame, 3mm toughened safety glass, and an optimised roof design, the ICON 6 6×8 combines dependable performance with clean, understated styling. A low-threshold sliding door makes moving trays, compost, and tools simple while preserving valuable growing space inside. Whether you’re upgrading from a smaller greenhouse or starting with bigger growing ambitions, this model provides reliable year-round usability.

Frame colour and glazing options available

Choose the ideal frame finish to suit your garden style. This greenhouse is available with a mill aluminium frame for a clean, low-maintenance look that stays neutral and understated over time, or select powder-coated black for a contemporary edge or powder-coated green for a classic, garden-blending finish.

Select the glazing option that matches your growing priorities. 3mm horticultural glass provides excellent light transmission and a traditional greenhouse feel, making it a popular choice for seed sowing, vegetables, and general plant growth. 3mm toughened safety glass offers the same high levels of light while adding extra strength and reassurance, breaking into small, blunt pieces if damaged, making it ideal for family gardens or more exposed locations. For improved insulation and durability, 4mm twin-wall polycarbonate glazing helps retain warmth, reduces heat loss, and performs well in harsher weather conditions.

Frequently asked questions

Do I need a base for my greenhouse?

In most cases, yes, a base is strongly recommended. A purpose-made greenhouse base makes installation far easier, ensures the structure sits level, and provides long-term stability. This helps protect both the frame and the glazing over time.

If your greenhouse is being installed onto an existing solid surface such as a concrete pad, brick base, or wall-mounted foundation, you may not require a separate steel base. However, where no suitable foundation already exists, a proper base is the safest and most straightforward option.

Occasionally, bases may be included as part of a special offer. If that applies, the option can simply be selected at zero cost when ordering.

Do I need professional installation?

All greenhouses are supplied with full instructions and many customers do successfully install them themselves. However, installation does require time, careful preparation, and suitable weather conditions. Many customers choose professional installation for added convenience and peace of mind. If you do opt for installation for your Icon 6 greenhouse, it is essential that the area is fully prepared ahead of time. This means the ground must be level, clear of debris, and easily accessible for the installation team.
